Bryan Wallace

Bryan Wallace has loved animals ever since he can remember. From the time he could read, he devoured Zoobooks magazines, Time/Life classics about wildlife, and even Jacques Custeau’s books!

He is currently Science Advisor to the Sea Turtle Flagship Program at Conservation International and Adjunct Assistant Professor at Duke University’s Division of Marine Science and Conservationn.

Research Interests

Applying insights from animal physiology and behavior to pertinent conservation issues; biogeography; movements and behavior; stable isotope analyses; diving physiology; thermoregulation; nest and egg physiology; fisheries bycatch.
